My invention relates to looin harness, and it relates more particularlyto means for mounting', in the heddle Jframes, the lieddl'es 407 vertical planes.

used for controlling the warp ends `for the i purpose of forming successive sheds of the warp during the operati-on of the loom.

The principal object of niy present invention is to provide improved Ineans'for'mounting the heddles in thelieddle frames which is particularly adaptable forV close installa-v tions for weaving tine fabrics, whereby the warp ends controlled by adjacent frames will pass the eyes ,of Vthe heddles more freely when the frames are reciprocated for the purpose of forming sheds, lthereby minimizing,`to a considerable extent, breakage of the4 warp ends. V` l I l f Heretofore, it has been recognized by those i skilled in the art that a great deal offbreak-A age ofv the warp ends is caused by reason ofthe resistance which occurs during the reciprocation of the various heddles in the looin, at the particular instant when the warp,

ends controlled by one of the vframes pass.

' the warp eyes of the'heddles mounted in another of the heddle frames, 'this occurring particularly in the Weaving of tine fabrics,

where the installation of the heddles ,in the frame is close, and where the warp is necessarily fine and easily broken` i Y To overcome the above mentioned diili culty, in some instances there were provided a plurality or' sets of lieddle frames, each set being operated in'unison to control one lset of the warp ends. This, however, was a more or less clumsy expedient, which led to the subsequent development of the mountingy of a plurality` oirsets of heddles in asingle frame, arranged in a plurality of separated Heretofore, Where two or more sets of heddles were mounted in a single frame, certain difficulties vexisted in connection with secur-k ing the heddle supporting rods in the frame;

and furthermore, the frames were of considerable thickness, so thaty in some instances the requisite number could not be used in an ordinary-loom. Y y

- The present invention i contemplates the provision of improved means for mounting a' 192s. sriairobesaczaf standard equipment of they loom when fit is] required to changeover toV a finer countfo'f the' warp.

The nature and characteristic*features of"l my present ';invention will be more readily understood fromthefollowingV description, f

taken' 'in connectionl withV the `accoinpanyiiig; drawings forming part hereof, in which:l f

n I Fig',y 4c? is an enlargedV horizontal,y section,v taken approximately'onthe line lltlof 'Figllia-nd f l' endof a pair of'heddle sup-porting rods constituting the lprincipal 'novel' portion of -my present invention.V y

Referring -to the drawings, the: heddle F'g.' 5- is a perspective View showing one* frame there shown consists "of the top' andv `bottom bars 6, connected'at their ends ,by1v

meansl O' the side strips ,7, which are secured to theV top and bottombars atthee'nds' thereoiv in any. preferredmanner. f3 j i f Extending from end to end of theV heddle frame, and= arranged vnear the topi and bottom bars, are lthe heddlesupporting barsS, upon which the -heddles 19 arelinounted. "Inthet present instance, there are-shown provided two of such bars at the'top, and two atthe bottomof the iframe, whereby two'setsof heddles 19inay be supported onF said bars 8.

f Near the end'of ea'chj of? the bars 8, the saine is oiset out of the planeof the inainportion thereof,y a'sY at9, andtlierefis also provided an extending portionlO, which passes through the aperture i 11 usuallyl provided; iii'- the end strips 7 of theirame-v or'thel support Aofthe' heddle bar`s; The ,extending"portioir10` of .its

, ertures 12 in the ends of the bars 8.

It willV here be noted that Vthe apertures 12 Vin the adjacent ends of the bars 8 preferably register with each other, so that each of the securing devices 13 serves to engage and secure the respective adjacent ends of a pair of the heddle bars 8 V(see Fig. 5)

For supporting the heddle bars intermediate their ends, and also for maintaining the same in their properspaced relationship, whereby the heddles of one set will not foul on the other, there are provided, at suitable locations, hook members 15, each having a pair of recesses 16 in which the heddle bars 8 are located.

The hook Vmembers 15 may be secured to the top and bott-om bars 6 in any preferred manner. In. the drawings, they are shownas being slidably mounted on auxiliary rods 17, which are preferably of non-circular cross section, and the apertures through whichthe rods 17 extend are complementally shaped, so as to keep the hook members 15 .from projecting beyond the faces of the frames,

The auxiliary rods 17 may be supported from the top and bottom bars 6 by means of screw eyes 18, suitably located for that purpose. i

It will be seen that there is thus provided improved means for mounting a'plurality of sets of heddles in a heddle frame, whereby the same may, if desired, be readily mounted in a heddle frame of standard construction.

.It will also be noted that when the present invention is employed, two or more sets of heddles may be mounted in a single frame without unduly increasing the, thickness thereof. y

Having thus described the nature andcharacteristic features of my invention, what I` claim as new and desire to secure by Lettersl Patent, is: v

In a loom harness, a harness frame comprising top and bottom bars, side strips connecting said bars at their ends, a plurality of heddle supporting bars arranged :at the top and bottomV of the frame, said'bars having their main or heddle supporting` portions spaced Vand having their end portions, offset from the respectivev planes of the main portions and thereby brought together and extending side by side through common yap-v ertures in the side stripsof the frame, the extending ends of the heddle supporting bars having registered apertures, and means for securing the heddle supporting bars compris- JOHN JACOB KAUFMANN.
